Local variable not working inside the for loop

[BadtoysWEF]

Hello!!
I love this project and it was the only reason I had to buy a dm42n. I would like to see this project in the HPprime which I think is better, however, I'm having the mentioned issue. I got the error "Bad Argument type". I'm using the local variable from the loop as an argument for the GET instruction. Here is the code:

«
@Poligon area by Gauss method
@GET THE DEPTH OF STACK AND DUPLICATE THE TOP AT THE BOTTOM
DEPTH
PICK
DEPTH
'n' STO
n ROLL
@build the matrix
1 n for  k
 Σ+ 
next
 ΣData 'M' STO
 
 @Gauss method
 1 n 1 - FOR k
    M { k 2} GET M k 1 + 1 2 �LIST GET * M { k 1} GET M 1 k + 2 2 ΣLIST GET * -                                                                     
        
    NEXT   
 DEPTH ��→LIST ΣLIST ABS .5 * "AREA" →TAG
 

{'ΣData' 'M' 'n' } PURGE

»

'AGAUSS' STO

I use a similar code in my HP50 and it works perfectly. Is there a bug or something that has not been implemented?

Thank you!!

This appears to be a bug to me since HP50g's GET would attempt to eval the content of the list when used as index.

For now you can explicitly build the list from k 2 2 ->List as a workaround.

I agree with @LdBeth, this looks like a bug in GET.
